Yes, EFI live will do it. No need to get another ecu or pcm for it. If you buy EFI live, you can get rid of the banks. EFI live is a much better tuning tool than Banks. EFI Live is good if you like to tinker with the settings. There is a lot of support with EFI live if you buy it through a vendor. You can download tunes to see what settings they change. Eventually I am going to get EFI Live, I just need to save up the money though. Seems like there is always something else that comes up though.
